Abstract [en]

Drum shearer plays an important role in the face production in longwall coal mines. Therefore, monitoring of this machine can lead the whole extraction operation to high level of productivity and safety. Availability is one of the most important measures for evaluation of the mining machineries. High availability of equipment can be helpful in satisfying the desired production goals. In this article the availability of drum shearer in an Iranian coal mine has been studied. For this purpose, the failure and maintenance data for a period of two years have been used. After data sorting and analysis, the inherent availability, achieved and operational availability of this machine have been calculated. The results show that the studied shearer machine performs in high level of availability. Nevertheless, the logistics delay time and administrative delays with the share of 25% of whole downtimes are so important influencing factors which should be controlled and planned to minimize it.
